A 2007 comparison of CMSes rated Plone highly in a number of categories (standards conformance, access control, internationalization, aggregation, user-generated content, micro-applications, active user groups and value).[23] However, as most of the major CMSes, including Plone, Drupal, WordPress and Joomla, have undergone major development since then, only limited value can be drawn from this comparison. Plone is available on many different operating systems, due to its use of platform-independent underlying technologies such as Python and Zope. Plone's Web-based administrative interface is optimized for standards, allowing it to work with most common web browsers, and uses additional accessibility standards to help users who have disabilities. All of Plone's features are customizable, and free add-ons are available from the Plone website.

Strengths and weaknesses

Since its release, many of Plone's updates and add-ons have come from its community. Events called Plone "sprints" consist of members of the community coming together for a week and helping improve Plone. The Plone conference is also attended and supported by the members of the Plone community. In addition, Plone has an active IRC channel to give support to users who have questions or concerns. Up through 2007, there have been over one million downloads of Plone. Plone's development team has also been ranked in the top 2% of the largest open source communities.

The community supports and distributes thousands of addons via company websites but mostly through PYPI and www.plone.org. There are currently 2149 packages available via PYPI for customizing Plone.[22]

Addons

Plone is built on the Zope application framework and therefore is primarily written in Python but also contains large amounts of HTML and CSS, as well as JavaScript.[19] Plone uses jQuery as its Javascript framework[20] in current versions, after abandoning a declarative framework for progressive enhancement called KSS.[21] Plone uses an XML dialect called ZCML for configuration, as well as an XML based templating language, meaning approximately 10% of the total source code is XML based.[19]

Languages

The name Plone comes from a band by that name and "Plone should look and feel like the band sounds".[18]

A large part of Plone's changes have come from its community. Since Plone is open source, the members of the Plone community regularly make alterations or add-ons to Plone's interface, and make these changes available to the rest of the community via Plone's website.

Version timeline

The Plone project began in 1999 by Alexander Limi, Alan Runyan, and Vidar Andersen. It was made as a usability layer on top of the Zope Content Management Framework. The first version was released in 2001. The project quickly grew into a community, receiving plenty of new add-on products from its users. The increase in community led to the creation of the annual Plone conference in 2003, which is still running today. In addition, "sprints" are held, where groups of developers meet to work on Plone, ranging from a couple of days to a week. In March 2004, Plone 2.0 was released. This release brought more customizable features to Plone, and enhanced the add-on functions. In May 2004, the Plone Foundation was created for the development, marketing, and protection of Plone. The Foundation has ownership rights over the Plone codebase, trademarks, and domain names. Even though the foundation was set up to protect ownership rights, Plone remains open source.[8] On March 12, 2007, Plone 3 was released. This new release brought inline editing, an upgraded visual editor, and strengthened security, among many other enhancements.[9] Plone 4 was released in September 2010.[10] Up to September 2007, there have been over 200 developers contributing to Plone's code. Plone won two Packt Open Source CMS Awards.[11]

Plone has a long tradition of development happening in so-called "sprints", in-person meetings of developers over the course of several days, the first having been held in 2003[5] and nine taking place in 2014. The largest sprint of the year is the sprint immediately following the annual conference. Certain other sprints are considered strategic so are funded directly by the Plone Foundation,[6] although very few attendees are sponsored directly. The Plone Foundation also holds and enforces all copyrights and trademarks in Plone, and is assisted by legal counsel from the Software Freedom Law Center.[7]
